The specs are o/k but there are no upstream channels being bonded. Have you tried powercycling the modem lately ?

Adding to EG, there’s a high pass filter on your drop,placed there by the maintainance team, blocking those upstream channels. At some point, they detected some kind of interference/ingress coming out of your house affecting the plant. Escalated to assist you getting a tech out
